Befuddled By Blue, Part Three

In Befuddled by Blue, Part One, we learned that blue light filters that can be used indoors don’t provide a significant reduction in the blue light that disrupts normal sleep patterns. We also learned that the science is not yet available to allow us to conclude that the small dose of blue light emitted from digital device screens is a significant risk to eye health. Yet, we believe that recommending lenses that can be used indoors to reduce high energy wavelengths is a good precautionary measure, as long as the patient is educated on the greatest threat for high energy light damage to the eye, the sun.
